问题     A simple idea supports science: "trust, but verify". Results should always be【C1】________to challenge from experiment. That simple but powerful idea has【C2】________a vast body of knowledge.【C3】________its birth in the 17th century, modern science has changed the world【C4】________ recognition, and overwhelmingly for the better.
    But success can【C5】________self-contentment. Modern scientists are doing too much trusting and not enough verifying, which does harm to both the whole of science and humanity.
    Too many of the【C6】________that fill the academic field are the result of inferior experiments or poor analysis. A rule of thumb among biotechnology venture-capitalists is that half of【C7】________research cannot be reproduced. Even that may be【C8】________. Last year researchers at one biotech firm, Amgen, found they could reproduce just six of 53 "landmark" studies in cancer research. Earlier, a group at Bayer, a drug company,【C9】________to repeat just a quarter of 67 similarly important papers. A leading computer scientist complains that three-quarters of papers in his subfield are nonsense.
    The reasons might lie in this: researchers are no longer willing to verify hypothesis investigated by other scholars since these papers have rare chance to be published. All this makes a poor foundation for an enterprise dedicated【C10】________discovering the truth about the world What might be done to shore it up? One【C11】________ should be for all disciplines to follow the example of those that have done most to tighten standards.
    【C12】________research protocols should be registered in advance and monitored in virtual notebooks. This would【C13】________the temptation to distort the experiment’s design so as to make the results look more【C14】________ than they are.【C15】________possible, trial data also should be open for other researchers to【C16】________and test.
    Science still【C17】________enormous respect. But its privileged【C18】________is founded on the capacity to be right most of the time and to correct its mistakes when it gets things wrong. And it is not as if the universe is short of【C19】________mysteries to keep generations of scientists hard【C20】________. The false trails laid down by inferior research are an unforgivable barrier to understanding.
【C19】
选项 A、untold
B、genuine
C、skeptical
D、incredible
答案B
解析 空格所在句意为“宇宙中并不缺少让数代科学家为之努力(keep…hard)……秘密”。从第三段论述的papers…are nonsense(科学研究都是空话)可以推断出，科学们要为之努力的应该是名符其实的秘密，故选B项genuine“真正的”。A项untold“未说过的”修饰“科学研究的秘密”显得过于随意。C项skeptical“可疑的”不能修饰“秘密”，从文中也无法推断秘密是否可疑。D项incredible“惊人的”，从上下文并无证据判断秘密是否惊人。
